Abstract: Various embodiments of restraint system pretensioning devices for use in land, air, and sea vehicles are described herein. In one embodiment, a seat unit for use in a military land vehicle or helicopter includes a stroking device that enables the seat to move downwardly in response to sudden movement. The seat unit also includes a seat belt or harness that extends around the occupant in the seat. Sudden movement of the seat in response to an explosion or hard landing causes a pretensioning assembly to automatically pretension the seat harness.

Abstract: Various embodiments of restraint harnesses for use in land, air, and sea vehicles are described herein. In one embodiment, for example, a restraint harness can include a first shoulder web, a second shoulder web, and a torso web. A first end portion of the torso web can include a buckle that is configured to engage a connector at a second, opposite end portion of the torso web. The restraint harness can further include first and second portions of a stiffening material attached to first and second portions of the first and second shoulder webs, respectively. The stiffening material can form the first and second shoulder webs into preformed openings with inverted U-like shapes.

Abstract: Buckle assemblies with swivel and dual release features and associated systems and methods are disclosed herein. In one embodiment, a buckle assembly is configured to detachably engage a web connector coupled to a first web. The buckle assembly includes a support structure coupled to a first release actuator, a second release actuator, and a swivel subassembly. The buckle assembly is configured to allow a user to detach the web connector from the buckle assembly via the first and/or second release actuators. Moreover, the swivel subassembly is configured to be coupled to a second web and to prevent the second web from twisting with reference to the buckle assembly.

Abstract: Buckle assemblies and associated connectors for use with child seats and other personal restraint systems are disclosed herein. A restraint system configured in accordance with one embodiment of the invention includes shoulder/lap webs which are slideably received in corresponding web connectors. Each of the web connectors includes a tongue portion that is configured to releasably interlock with the other tongue portion before the interlocking tongue portions are simultaneously inserted into the buckle assembly as a unit. The buckle assembly is configured to receive and engage the interlocking tongue portions only when the tongue portions have been properly mated together prior to insertion into the buckle assembly.
